How to clean electrical contacts

How do I remove oxidation and rust?

You can remove rust and oxidation either through mechanical or chemical methods. For sensitive contacts, you can use a brass or steel brush to scrub off oxidation, as it is the common method and circumstances for doing it.

Scrubbing the area will do many wonders, but one needs to be careful when doing it to avoid damage to the electrical contacts. In this situation, the recommendation to use some cleaner is allowed, which will help you reach out to tight areas to soften the contaminants and ensure your device can work optimally.

Things to look for when choosing contact cleaner

There are some important things that you need to consider when choosing a contact cleaner.

1. Flammability

Most of the contact cleaners you will get today contain alcohols and hydrocarbon solvents, making them highly flammable. The cleaners are very effective, but they pose a high safety hazard, which is the reason you should never use them anywhere near open flames or sparks.

So, you should be careful when choosing the contact cleaner and ensure you choose the safe one to use, to be aware of safety issues.

2. Dielectric strength

If you intend to clean contacts while the power is still on, choose a cleaner with the highest dielectric strength possible. Before spraying anything onto the circuits you’re attempting to clean, always know the amperage and voltage of the circuits you’re attempting to clean, and evaluate the suitability of any cleaner in your application.

The maximum electric field that a material can withstand before its insulating properties degrade is called dielectric strength. In other words, the lower the dielectric strength, the more likely it will break down and allow electricity to flow through it, resulting in a short circuit and/or a major safety issue.

3. Plastic/rubber compatibility

While the contact surfaces of connectors are metals, they are frequently housed in plastics, with rubber gaskets to seal everything from the outside environment. If the solvent used in a contact cleaner is incompatible with the plastic, it can cause small cracks, embrittlement, or softening. Rubber seals may swell, shrink, or even dissolve if exposed to a harsh solvent.
